Nachiket : Which version of petsc is used? Did you run the code in sequential?
> ------------------------------------ > [0]PETSC ERROR: Arguments are incompatible! > [0]PETSC ERROR: MatMatMult requires A, seqdense, to be compatible with B, > seqdense! [0]PETSC ERROR: MatMatMult() line 8601 in /opt/petsc/petsc-3.3-p2/src/mat/interface/matrix.c The line (8601) does not match the latest petsc-3.3 and petsc-dev. I cannot reproduce this error from the latest petsc-3.3 and petsc-dev. The error complains about a failure to find MatMatMult_SeqDense_SeqDense(). Can you update to the latest petsc-3.3 or petsc-dev and see if your code still crashes? Hong > I am trying to multiply the transpose of a matrix with another matrix using > matmatmult.
